  • Patent number: 8941247
    Abstract: In a packaging structure for a microelectromechanical-system (MEMS) resonator system, a resonator-control chip is mounted on a lead frame having a plurality of electrical leads, including electrically coupling a first contact on a first surface of the resonator-control chip to a mounting surface of a first electrical lead of the plurality of electrical leads through a first electrically conductive bump. A MEMS resonator chip is mounted to the first surface of the resonator-control chip, including electrically coupling a contact on a first surface of the MEMS resonator chip to a second contact on the first surface of the resonator-control chip through a second electrically conductive bump. The MEMS resonator chip, resonator-control chip and mounting surface of the first electrical lead are enclosed within a package enclosure that exposes a contact surface of the first electrical lead at an external surface of the packaging structure.

  • Publication number: 20140101303
    Abstract: A method is provided in one example embodiment and includes creating an initial sample set comprising a plurality of notification messages, where each of the notification messages is associated with one of a plurality of bearers each of which has a first parameter associated therewith. The method further comprises prioritizing the notification messages of the initial sample set according to a value of the first parameter of the associated bearer to create a prioritized sample set and optimizing the prioritized sample set to create an optimized sample set. The method further comprises applying a throttle factor to the optimized sample to remove a number of low priority notification messages from the prioritized sample set to create a final set of notification messages to be transmitted to a network element.

  • Patent number: 8669664
    Abstract: A stacked die package for an electromechanical resonator system includes an electromechanical resonator die bonded or fixed to a control IC die for the electromechanical resonator by, for example, a thermally and/or electrically conductive epoxy. In various embodiments, the electromechanical resonator can be a micro-electromechanical system (MEMS) resonator or a nano-electromechanical system (NEMS) resonator. Certain packaging configurations that may include the chip that contains the electromechanical resonator and the control chip include chip-on-lead (COL), chip-on-paddle (COP), and chip-on-tape (COT) packages. The stacked die package may provide small package footprint and/or low package thickness, and low thermal resistance and a robust conductive path between the dice.

  • Publication number: 20120170103
    Abstract: We describe a method of fabricating an optical MEMS spatial light modulator (SLM). The method comprises providing an optical MEMS SLM wafer bearing multiple optical MEMS SLM devices and spin coating a glass wafer with an organic adhesive, in some preferred embodiments benzocyclobutene. The adhesive is patterned, preferably by uv lithography, to define multiple ring-shaped bond lines each sized to fit around one of the SLM devices, and the glass wafer is then bonded to the MEMS SLM wafer, preferably at a temperature of between 100° C. and 450° C., such that each of the ring-shaped bond lines encompasses a respective SLM device. A portion of the glass wafer adjacent an SLM device is then removed to reveal electrical connectors to the device and the devices are tested before dicing and packaging, to enable selective packaging of working devices.
